gravitation

Provides color-illustrated, step-by-step instructions for ten simple experiments designed to teach students about gravity.

Describes how force and gravity set objects in motion and how they influence the velocity and direction of moving objects. Also discusses the perception and measurement of motion.

This book traces our knowledge of gravity over time and in different cultures through biographical accounts and describes experiments and conclusions drawn from experiments.

Classroom demonstrations, animation, and live-action footage illustrate the interactions of the sun, the earth, and its satellite (the moon). Students will find out about the relative sizes of the earth, sun, and moon, the difference between rotation and revolution, and the importance of gravity.

Introduces young readers to the basics of gravity, covering early observations, controversies, Einstein's revelation, the Big Bang, and more.

Simple experiments demonstrate the laws of gravity.

An introduction to gravity, explaining what it is and how it works on Earth and in outer space. Includes an activity, fun facts, and a glossary.
